Figure 4 Effect of SIN on T-bet and GATA-3 location in placental tissues of RSA mice. (A) Immunohistochemical staining for the expression of T-bet (a–c) and GATA-3 (d–f) in the placenta of the control (a, d), RSA (b, e) and SIN-treated (c, f) mice. Magnification: 400×. (B) H-score for the immunohistochemical staining intensity of T-bet, GATA-3, and T-bet/GATA-3 ratio. Data are expressed as mean±S.E.M. * P<0.05, compared with the control group; # P<0.05, compared with the RSA group.
